New records from 41 localities are given for six species of vespertilionid bats, namely Myotis myotis (Borkhausen, 1797), M. blythii (Tomes, 1857), M. capaccinii (Bonaparte, 1837), Pipistrellus pipistrellus (Schreber, 1774), P. kuhlii (Kühl, 1819) and Barbastella barbastellus (Schreber, 1774). The diploid number of chromosomes (2n) and the total numbers of autosomal arms (NFa) were determined as 2n= 44, NFa= 50 for M. myotis, M. blythii, M. capaccinii, P. pipistrellus, P. kuhlii and as 2n= 32, NFa= 50 for B. barbastellus.

A new record of the Marbled Polecat, Vormela peregusna, is given from south-eastern Turkey along with karyological and morphological including bacular characteristics. The specimen has a shorter black band at the tip of the tail than in a specimen examined from western Turkey and thus takes an intermediate position between specimens from Jordan and from western Turkey. Whereas the diploid chromosome number is the same as in Caucasia, Syria, western Turkey and Romania, the fundamental chromosome number (FN) and the number of autosomal arms (NFa) is higher than in Western Turkey, but the same as in Syria.

The taxonomic status and diagnostic characteristics of Meriones tristrami blackleri, M. t. lycaon, M. t. intraponticus, M. t. bodenheimeri and M. t. bogdanovi are discussed, based on material collected in Turkey. According to biomeţric and morphological comparisons, the specimens from southeastern and eastern Anatolia were found to be closer to bodenheimeri and bogdanovi than to lycaon. The white tail tip of blackleri, the dorsal colour and baculum shape of lycaon, the white incisors of intraponticus, and the short hind foot and the ear length of bodenheimeri are characteristics that distinguish these taxa from one other. The diploid number of chromosomes is 72 in M. tristrami. However, the fundamental number is 76 in blackleri and 82 in lycaon, intraponticus and bodenheimeri.
